METHOD AND APPARATUS FOR INDUCTIVELY TRANSFERRING AC POWER BETWEEN A CHARGING UNIT AND A VEHICLE
First Claim
1. An inductive charging system for a battery charger on a vehicle, comprising(a) a transformer including a stationary primary coil and a secondary coil mounted on the vehicle;
- (b) a power source connected with said transformer primary coil to generate a magnetic field which induces voltage in said secondary coil;
(c) a controller connected with said power source for adjusting the voltage delivered to said primary coil; and
(d) a feedback loop between said secondary coil and said controller for delivering a secondary voltage signal to said controller, said controller continuously adjusting said power source in order to maintain the secondary output voltage at a predetermined value.

Abstract
An inductive charging system for vehicle battery chargers includes a transformer having a stationary primary coil and a secondary coil mounted on the vehicle. The primary coil is mounted in a charging station and has a power source connected therewith. When the vehicle is parked adjacent to the charging station, the secondary coil on the vehicle is proximate to the primary coil in the station. The power source is activated to deliver current to the primary coil which generates a magnetic field to induce a voltage in the secondary coil. A controller is connected with the power source to adjust the voltage delivered to the primary coil. A feedback loop between the secondary coil and the controller delivers a secondary voltage signal to the controller which continuously adjusts the power source in order to maintain the secondary output voltage at a predetermined value.
